please tell me how to remove this.
kind regards,

Jewelers are trained and experienced in what materials are safe to apply to gold and sapphire, and will have ultrasonic jewelry cleaner ⇦ this on eBay or Amazon [affil links] to accelerate the cleaning process. I wouldn't try this at home.

citric acid ⇦ this on eBay or Amazon [affil links] is an extremely effective and highly safe answer to your problem. It will dissolve the lime matrix which hards the concrete and make cleaning and removal easy and friendly..find a local solution of a citric acid cleaner (don't confuse with citrus, as in cleaner). You can also contact us for this product..No worries!
